Hi All,
I tend to learn the hard way to preface this. I soldered in some tri-clamp fittings to a Brewer's Best kettle. My critical mistake was not wiping off the excess flux and leaving the kettle for months. There are some corrosion spots from the flux that was not wiped away. I've tried vigorously scrubbing it away with BKF, but the etched spots remained and rust quickly returned. I'm now considering attempting to sand and re-passivate the metal, but I wanted to seek out a little advice before doing so.
Would sanding going from 240 up to 400, then 600 and re-passivating with citric acid fix this issue? Any recommendations or tips would be appreciated.
Thanks!
